Remote relay beacon. Dellis Tantor plants a remote relay beacon. Remote relay beacons were tall communication structures which could retransmit data through a line-of-sight network. Once deployed, the beacons would search out any nearby beacons and establish a laser connection thourgh which data could be transmitted.
Typically the relay will operate a switch (relay contact) to indicate that an input has surpassed a setting, or the relay can provide notification through visual feedback such as a meter or LED. One advantage of electronic or microprocessor relays is an ability to communicate with a network or a PLC. As an example, a thermostat can be evaluated using the diagram in Figure 1. The input that is measured is temperature and the protection relay input device is the temperature sensor. The user sets the desired temperature setting (pick-up level). The relay measures the existing air temperature and compares it to the setting.
